• DC traffic > 5 ZB in 2015, much of that being intra-DC• Inter-DC traffic growth to increase at a higher rate than intra-
DC• DC SDN based networks
Data center interconnect (DCI) becoming a significant portion of overall cost and power consumption
Significant growth of DCI market for geographically dispersed sites
100G in deployment now, 200G/400G on the horizon

Data Center Interconnect Challenges Power efficiency (pJ/bit or mW/Gb/s)
Port density (Gb/s/mm2)
Reach (km)
Cost efficiency ($/Gb/s)

Technologies Enabling Future DC Client Interconnects
Cu twinax
MM/SM VCSELs
SM Si Photonics SM CWDM
PAM-4 modulation
